Re: NSTextField setStringValue nil value

[Fred Kiefer]

Have you done more tests on this? Who is raising the exception, the text
field, the control or the cell? Or will I have to do these tests myself?

In [NSCell-setStringValue:] we have this code:

if (aString == nil)
{
NSDebugMLLog (@"MacOSXCompatibility",
@"Attempt to use nil as string value");
}

Did this get triggered in your case? And if not, why not? If you are
interested in Mac compatibility you could run your code with the option
--GNU-Debug=MacOSXCompatibility

Hope this helps,
Fred

I was running without that flag... so is it expected that GNUstep
behaves slightly different? IN case, I'm fine, else I will prepare a
testcase as you request. It won't be difficult. IN the meanwhile I fixed
the application where this was happening.

I think the point is that this flag triggers additional debug output.
